Objective To investigate the application value of transnasal intestinal obstruction catheter under endoscope in relieving postoperative intestinal obstruction.Methods A retrospective analysis was performed on 52 cases of postoperative intestinal obstruction who were admitted into our hospital from January 2017 to March 2018. Among them

26 cases were treated with intestinal obstruction catheter through endoscope (the observation group)

and the other 26 cases were treated with nasogastric catheter for gastrointestinal decompression (the control group).The relief time of abdominal symptoms after catheterization

the time of defecation

the relief time of obstruction indicated by CT

the time of intubation and the time of hospitalization were respectively compared in the 2 groups to observe the clinical efficacy.ResultsIn the observation group

the status of abdominal symptoms after 24 hours and exhaust and defecation condition after 48 hours were better than those in the control group.The time of obstruction remission

average days of catheterization and length of hospital stay were significantly shorter than those in the control group

with statistically significant differences (P<0.05).Conclusion Transnasal intestinal obstruction catheter can effectively relieve postoperative intestinal obstruction and prevent recurrence of adhesive intestinal obstruction.
